[IA64-SGI] Fix sn_flush_device_kernel & spinlock initialization
This patch separates the sn_flush_device_list struct into kernel and
common (both kernel and PROM accessible) structures. As it was, if the
size of a spinlock_t changed (due to additional CONFIG options, etc.) the
sal call which populated the sn_flush_device_list structs would erroneously
write data (and cause memory corruption and/or a panic).
This patch does the following:
1. Removes sn_flush_device_list and adds sn_flush_device_common and
sn_flush_device_kernel.
2. Adds a new SAL call to populate a sn_flush_device_common struct per
device, not per widget as previously done.
3. Correctly initializes each device's sn_flush_device_kernel spinlock_t
struct (before it was only doing each widget's first device).
